Article Abstract

Purpose: This observational study was based on a series of clinical cases in which failure of sinus augmentations occurred in patients who received prophylactic clindamycin therapy.

Materials And Methods: Between the years 2006 and 2010, a retrospective observational study was performed. The study consisted of 1,874 patients (723 males and 1,151 females) in whom sinus augmentations were performed prior to placement of dental implants.

Results: In nine (0.48%) patients (four males and five females), infection of the graft material inside the sinus floor occurred, and six patients developed an abscess in the site of surgery, 4 to 6 weeks postoperatively. In three patients, a buccal fistula with pus draining was observed 5 to 8 weeks postoperatively. In all patients, the source of infection was from the grafted material within the sinus. A common manifestation in all nine patients was that they had self-reported penicillin allergy and had been prescribed clindamycin (300 mg every 6 hours for 10 days).

Conclusion: Prophylactic clindamycin therapy following sinus augmentation procedures seems to be a risk factor for infections and loss of grafting material following these surgical techniques.

Introduction: Amivantamab plus lazertinib significantly improved progression-free and overall survival versus osimertinib in patients with previously untreated, EGFR-mutant advanced NSCLC. EGFR-targeted therapies are associated with dermatologic adverse events (AEs), which can affect quality of life (QoL). COCOON was conducted to assess prophylactic management and improve treatment experience.

Antimicrobial prophylactic strategies in vNOTES: No consensus, but what do we know?

Aim: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) combines vaginal and laparoscopic techniques and is increasingly used in gynecologic surgery. Given the lack of standardized guidelines for antibiotic prophylaxis, this review aims to evaluate infection rates, current prophylactic practices, and recommendations.

Method: A literature search was conducted in PubMed/MEDLINE and the Cochrane Library using Medical Subject Headings (MeSH) and keywords such as "v-NOTES," "infection," "prophylaxis," and "antibiotics".

Surgical site infections (SSIs) are a significant postoperative complication in instrumented lumbar spine surgery, and the selection and duration of appropriate prophylactic antibiotics are key to their prevention. The aim of our study was to evaluate the effectiveness of various prophylactic antibiotics, primarily cefazolin and clindamycin, as well as the role of the duration of antibiotic prophylaxis in the development of SSI in instrumented lumbar spine surgeries through retrospective analysis. We performed a retrospective analysis of data from 915 patients who underwent instrumented lumbar spine surgery between 2016 and 2024 in a university center database.

Background: Periprosthetic joint infection (PJI) of the shoulder is a devastating complication following total shoulder arthroplasty (TSA). The majority of literature regarding antibiotic choice for TSA is from accompanying literature in other orthopedic subspecialties. The purpose of this study was to delineate the relationship between various perioperative antibiotics, including local, topical vancomycin, and their potential protective effect on PJI following shoulder arthroplasty.

Background: Maxillofacial infections (MIs), particularly surgical site infections (SSIs) following orthognathic surgery, represent a significant clinical concern due to their potential severity and impact on treatment outcomes. Although antibiotic prophylaxis is standard practice, growing bacterial resistance-especially in penicillin-allergic patients-challenges the effectiveness of alternative regimens such as clindamycin.

Material And Methods: This retrospective study analyzed 100 consecutive patients who underwent orthognathic surgery between 2022 and 2023, performed by the same surgical team.
